15. Studies on immunostimulatory effect of efcovida powder on Cyclophosphamide-induced immunosuppression in mice
Main Article Content
Abstract
To evaluate the immunostimulatory activity of Efcovida powder, we induced immunosuppression in Swiss mice by cyclophosphamide (CP). Efcovida powder at two doses of 60 mg/kg b.w and 120 mg/kg b.w were administered orally for seven consecutive days to animals. CP (200 mg/kg i.p.) was injected on the 4th day. The result showed that Efcovida powder at the dose of 60 mg/kg b.w only posed an immunostimulating potency in the cyclophosphamide-induced immunosuppression model while Efcovida powder at the dose of 120 mg/kg b.w significantly ameliorated the effects of CP on delayed-type hypersensitivity (DTH) response, leukocyte quantity, relative thymus weight, serum IL-4, IL-6 concentration, and micro-histological images of spleen and thymus. This suggested the potential of Efcovida powder to treat immunosuppression diseases in clinical practice.
